To aillwlwm; it may concern:

Be it known that I,` IEA G. MITCHELL, a citizen of the United States, residing at Meeker, in the county of Rio Blanco and State of Colorado,y have invented certain new and useiiul'lrnprovements in Pumping Apparatus,- oli which the following is a specification, reference being had therein to the accompanying. drawings. l i

My invention'relatesv to irrigation-pumps, and has for itsl objects the provision oi' means for the utilization of an available comparatively large quantity of water to elevate a small proportiony of its' mass to a greater height,` whereby large areas of elevated arid land are-now without practicable means of irrigation may be reel-aimed and rendered fertile at a small initial outlay and an inconsiderable cost of maintenance I accomplish this object by means of lforcepuirnps driven water-power and wholly autorriatic' in action, thedetails of construction and operation of whichv will be hereinafter more fully described and claimed in connec tionl 'with the accompanying drawings, in whicht Figure lis aside elevationwith the motor in equilibrium. Fig. 2 is a similar view at the end oi' a stroke. Fig. 3 is a vertical cross-section on the line 31 3- oiFigt2. Fig. 4 is a perspective view of one of the crank-arms and showing a section of oneof the valves. Fig. 5v is` a detail? view of one end of one of the vallve-operating rods. Fig.` 6 is a plan view ofonek ofthe valves, and Fig. 7 is a view of the valve-box with the end removed.

d In the embodiment of the invention shown a suitable' framework 1, arranged beneatha water-supply flume 2, serves as a support for a rock-shaft 3', upon which is balanced a walking-beam 4,. the two arms of which) are connected near its bearing by rods /wilth thefpump-pistons 6', Working in cyline ders-7, the upper portion of the cylinders comnnflnicati-ng by pipes S Withthe dischargepipe 9, leading to the elevated land to be irrigated.. i l l each extremity of the beam .4 in arms 1i() is swunga water-bucket Il by pintles 12, ears 13 projecting beyond the pintles alongside the buck-et Lugs 14 extend outwardly from the sides of the buckets andy normally rest upon the ears 13, whereby the buckets a position to engage the -lugs 14 to tilt the bucket as the beam end descends.

Above the rock-shaft 3 an arm 16 extend-s upwardly at right angles from the beam and has secured thereon across-bar 17 adjustable by means of the set-screw 18, to the ends of which crossfbar connecting-rods 19`are' pivoted at 20. The other end of eachrod `19 passes through a sleeve 21, within which has longitudinal play limited by the collars 2`2,se cured at each end of the sleeve to the* rod 19 by set-screws 23.

Directly above each bucket `11 and at the side of the Hume 2 isy arrari'gedy a valve-box 24, receiving. water from the llume andi discharging the same downthrough the spout 25 in its bottom t0 the bucket The' discharge-opening is controlled by 4a valve 26, arranged as a segment iLesha'ped in cross-section, of boiler-iron, with a rubber bearing-face 27. This Valve swings from a @pivot 28, which pivot is extended through the valvebox side and provided with a crank-arm 2'9', pivoted by a pin 30 tothe sleeve 21.y ,Y Journaled in a fixed portionof the frame 1 is the shaft 31 of a water-whee'lllconnected by a pitman 33 with one arm of the beam 4 and receiving a constant supply of water from the iiume 2v by the' pipe or closed trough 34, the quantity of water supplied to the wheel beingregulable by the valve 35. The shaft 3,1 of the water-wheel 32 also carries a ily-wheel 36; 4

Theo eration is as follows: Thewaterbeing led tromthe flume 2 through the pi e or closed trough 34 to the wheel 32, the walkingbeam is moved from the position shown in Fig. 1 until one end rises to a point immediately beneath the spout 25. During this movement the extremity of the arm li'ymoves through the arc oil a circle, carryingthe connecting-rod 19 to-the^right through the sleeve 21 until the'outer coll`ar22 strikes theend of the sleeve, when the valve is opened and the bucket quickly filled. That end of tihe'b'earn then descends, the valve closing by a reverse movement, and at the samel time the opposite end of the beam ascends with its bucket. When the bucket in its downward course reaches the trip 15, the lugs 14 are caught and IOO , beyond the opening to spout when it descends to close said opening, I provide a lug or guard 39, and to accelerate the speed of the valve in closing to avoid waste of water, an arm 40 is mounted on the crank-arm 29 and 'a weight 41 is slidably and adjustably mounted on the-arm by a set-screw or any other suitable means.

It will be seen that the weight of the water alternately applied and removed at the ends of the walking-beam causes an oscillation of the beam and operation oit' the pumps to supply the water to distant or elevated points in a very eilicient and economical manner, the water-wheel with its fly-wheel serving to carry the beam past any dead-center and as a starting medium as well as materiallyassist-` ing in the continuation of the pumping.

The time at which the valves are open and closed and the extent of opening can be accurately gaged, as will be readily understood, by raising and lowering the cross-bar 17 on the arm 16 and by changing the position of the collars 22 on the rods 19.

Where desirable, the device can be arranged with two walking-beams side by side 'with a corresponding arrangement of valveboxes, as shown in Fig. 3, and in other cases a single walking-be am will be su'Hicient, with but one set of valve-boxes arranged at one side of the flume or directly beneath the same, as will be obvious.

Wherefore, having thus fully described my invention and the manner of its operation, what I claim as new, and desire to secure by Letters Patent, is-
